The following tables, groups, and variables are supported in this MIB.
| Table/Group | Supported Variables | Comments |
|---|---|---|
| entityPhysicalTable | entPhysicalndex | The index for this entry. |
| entPhysicalDescr | A textual description of physical entity. This object should contain a string that identifies the manufacturer's name for the physical entity and should be set to a distinct value for each version or model of the physical entity. | |
| entPhysicalVendorType | An indication of the vendor-specific hardware type of the physical entity. Note that this is different from the definition of MIB-II's sysObjectID. An agent should set this object to an enterprise-specific registration identifier value indicating the specific equipment type in detail. The associated instance of entPhysicalClass is used to indicate the general type of hardware device. If no vendor-specific registration identifier exists for this physical entity, or the value is unknown by this agent, then the value { 0 0 } is returned. | |
| entPhysicalContainedIn | The value of entPhysicalIndex for the physical entity that 'contains' this physical entity. A value of zero indicates this physical entity is not contained in any other physical entity. Note that the set of 'containment' relationships define a strict hierarchy; that is, recursion is not allowed. In the event that a physical entity is contained by more than one physical entity (e.g., double-wide modules), this object should identify the containing entity with the lowest value of entPhysicalIndex. | |
| entPhysicalClass | An indication of the general hardware type of the physical entity. An agent should set this object to the standard enumeration value that most accurately indicates the general class of the physical entity, or the primary class if there is more than one entity. If no appropriate standard registration identifier exists for this physical entity, then the value 'other(1)' is returned. If the value is unknown by this agent, then the value 'unknown(2)' is returned. | |
| entPhysicalParentRelPos | An indication of the relative position of this 'child' component among all its 'sibling' components. Sibling components are defined as entPhysicalEntries that share the same instance values of each of the entPhysicalContainedIn and entPhysicalClass objects. | |
| entPhysicalName | The textual name of the physical entity. The value of this object should be the name of the component as assigned by the local device and should be suitable for use in commands entered at the device's 'console'. This might be a text name (e.g., 'console') or a simple component number (e.g., port or module number, such as '1'), depending on the physical component naming syntax of the device. If there is no local name, or if this object is otherwise not applicable, then this object contains a zero-length string. Note that the value of entPhysicalName for two physical entities will be the same in the event that the console interface does not distinguish between them, e.g., slot-1 and the card in slot-1. | |
| entPhysicalHardwareRev | The vendor-specific hardware revision string for the physical entity. The preferred value is the hardware revision identifier actually printed on the component itself (if present). Note that if revision information is stored internally in a non-printable (e.g., binary) format, then the agent must convert such information to a printable format in an implementation-specific manner. If no specific hardware revision string is associated with the physical component, or if this information is unknown to the agent, then this object will contain a zero-length string. | |
| entPhysicalFirmwareRev | The vendor-specific firmware revision string for the physical entity. Note that if revision information is stored internally in a non-printable (e.g., binary) format, then the agent must convert such information to a printable format in an implementation-specific manner. If no specific firmware programs are associated with the physical component, or if this information is unknown to the agent, then this object will contain a zero-length string. | |
| entPhysicalSoftwareRev | The vendor-specific software revision string for the physical entity. Note that if revision information is stored internally in a non-printable (e.g., binary) format, then the agent must convert such information to a printable format in an implementation-specific manner. If no specific software programs are associated with the physical component, or if this information is unknown to the agent, then this object will contain a zero-length string. | |
| entPhysicalSerialNum | The vendor-specific serial number string for the physical entity. The preferred value is the serial number string actually printed on the component itself (if present). On the first instantiation of a physical entity, the value of entPhysicalSerialNum associated with that entity is set to the correct vendor-assigned serial number, if this information is available to the agent. If a serial number is unknown or non-existent, the entPhysicalSerialNum will be set to a zero-length string instead. Note that implementations that can correctly identify the serial numbers of all installed physical entities do not need to provide write access to the entPhysicalSerialNum object. Agents that cannot provide non-volatile storage for the entPhysicalSerialNum strings are not required to implement write access for this object. Not every physical component will have a serial number, or even need one. Physical entities for which the associated value of the entPhysicalIsFRU object is equal to 'false(2)' (e.g., the repeater ports within a repeater module) do not need their own unique serial numbers. An agent does not have to provide write access for such entities and may return a zero-length string. If write access is implemented for an instance of entPhysicalSerialNum and a value is written into the instance, the agent must retain the supplied value in the entPhysicalSerialNum instance (associated with the same physical entity) for as long as that entity remains instantiated. This includes instantiations across all re-initializations/reboots of the network management system, including those resulting in a change of the physical entity's entPhysicalIndex value. | |
| entPhysicalMfgName | The name of the manufacturer of this physical component. The preferred value is the manufacturer name string actually printed on the component itself (if present). Note that comparisons between instances of the entPhysicalModelName, entPhysicalFirmwareRev, entPhysicalSoftwareRev, and the entPhysicalSerialNum objects are only meaningful amongst entPhysicalEntries with the same value of entPhysicalMfgName. If the manufacturer name string associated with the physical component is unknown to the agent, then this object will contain a zero-length string. | |
| entPhysicalModelName | The vendor-specific model name identifier string associated with this physical component. The preferred value is the customer-visible part number, which may be printed on the component itself. If the model name string associated with the physical component is unknown to the agent, then this object will contain a zero-length string. | |
| entPhysicalAlias | Not supported. | |
| entPhysicalAssetID | Not supported. | |
| entPhysicalIsFRU | This object indicates whether or not this physical entity is considered a 'field replaceable unit' by the vendor. If this object contains the value 'true(1)', then this entPhysicalEntry identifies a field replaceable unit. For all entPhysicalEntries that represent components permanently contained within a field replaceable unit, the value 'false(2)' should be returned for this object. | |
| entPhysicalMfgDate | This object contains the date of manufacturing of the managed entity. If the manufacturing date is unknown or not supported, the object is not instantiated. The special value '0000000000000000'H may also be returned in this case. | |
| entPhysicalUris | This object contains identification information about
the physical entity. The object contains URIs; therefore, the syntax of this object
must conform to RFC 3986. Multiple URIs may be present and are separated by white
space characters. Leading and trailing white space characters are ignored.If no URI
identification information is known about the physical entity, the object is not
instantiated. A zero-length octet string may also be returned in this case.
Note: This object has read-write permission, but is implemented with read-only
mode. Write operation is not supported.
|
|
| entPhysicalUUID | This object contains identification information about the physical entity. The object contains a Universally Unique Identifier, the syntax of this object must conform to RFC 4122, Section 4.1. A zero-length octet string is returned if no UUID information is known. | |
| entAliasMappingIdentifier | The value of this object identifies a particular conceptual row associated with the indicated entPhysicalIndex and entLogicalIndex pair.Because only physical ports are modeled in this table, only entries that represent interfaces or ports are allowed. If an ifEntry exists on behalf of a particular physical port, then this object should identify the associated ifEntry. For repeater ports, the appropriate row in the 'rptrPortGroupTable' should be identified instead. | |
| entPhysicalChildIndex | The value of entPhysicalIndex for the contained physical entity. | |
| entConfigChange | An entConfigChange notification is generated when the value of entLastChangeTime changes. It can be utilized by an NMS to trigger logical/physical entity table maintenance polls. An agent should not generate more than one entConfigChange 'notification-event' in a given time interval (five seconds is the suggested default). A 'notification-event' is the transmission of a single trap or inform PDU to a list of notification destinations. If additional configuration changes occur within the throttling period, then notification-events for these changes should be suppressed by the agent until the current throttling period expires. At the end of a throttling period, one notification-event should be generated if any configuration changes occurred since the start of the throttling period. In such a case, another throttling period is started right away. An NMS should periodically check the value of entLastChangeTime to detect any missed entConfigChange notification-events. | |
| entityGeneral | entLastChangeTime | The value of sysUpTime at the time a conceptual row is created, modified, or
deleted in any of these tables:
